An NHC‐Coordinated Silicon/Sulfur Analogue of an Acyl Carbene

open access: yesAngewandte Chemie, EarlyView.
An NHC complex of an Si/S analogue of an acyl carbene is synthesized by the reaction of a disilyne with a cyclic thiourea. The observed Si2S three‐membered ring with unsymmetrical Si─S distances and a Si─Si single bond is consistent with intramolecular coordination of the silathioacyl sulfur to the silylene center.

T‐Shaped Stibenium(III) Cation: Hydrostibination Without Sb─H Bond

open access: yesAngewandte Chemie, EarlyView.
A cationic, structurally constrained stibenium platform mediates anti‐Markovnikov hydrostibination of alkenes via element–ligand cooperativity (ELC), thereby bypassing the need for weak Sb─H bonds. ABSTRACT The hydrostibination of alkenes represents a largely underdeveloped transformation, owing to the intrinsic lability of the required Sb─H reagents ...

Decouple H2O2 Electrosynthesis From Microenvironmental Decomposition via Atomic Site Density Engineering

open access: yesAngewandte Chemie, EarlyView.
Using defect‐rich Co‐N2O2 single‐atom catalysts as a model system, this work reveals that atomic site density governs the competition between H2O2 electrosynthesis and microenvironmental decomposition during 2e−‐ORR. Optimised site isolation suppresses HPRR and HDR, thereby establishing a site‐density principle to balance H2O2 formation and ...

Tuning the Mechanical Properties of Crosslinked Copolymers via Sequence and Solvent‐Selective Swelling for Vat Photopolymerization

open access: yesAngewandte Chemie, EarlyView.
Polymer sequence and solvent selectivity independently modulate pendant‐vinyl accessibility during photocuring, trapping different topologies in CLIP and controlling mechanical properties. ABSTRACT Block copolymers (BCPs) offer distinct advantages for vat photopolymerization by enabling mechanically programmable network structures through microphase ...

Water, Alcohols, Amines, and Amides as Formal Hydrogen‐Atom‐Transfer Reagents Through Activation With Redox‐Active Lewis Acids

open access: yesAngewandte Chemie, EarlyView.
Protic molecules containing strong O─H or N─H bonds typically resist hydrogen‐atom abstraction because of the high reactivity of the resulting heteroatom‐centered radicals. However, association of the protic molecules with redox‐active Lewis acids can provide powerful hydrogen‐atom donors or proton‐coupled‐electron‐transfer reagents.
